Question

Point T is the midpoint. If PT=5x+3 and TQ=7s-9, then what are the values of PT and TQ?

Answer 1

PT = 33

TQ = 33

Explanation:

5x + 3 7x - 9

P-----------------T-------------------Q

• PT = TQ

• 5x + 3 = 7x - 9
• 3 + 9 = 7x - 5x
• 12 = 2x
• x = 12 / 2
• x = 6

solve for PT:

• 5x + 3
• 5(6) + 3
• 33

solve for TQ:

• 7x - 9
• 7(6) - 9
• 33
